I know it is a rather odd question, but it is an important one. People like myself who study NLP (neuro-linguistic programming) understand that repeated words and phrases, no matter how innocent or simple they may be, may be interpreted by the brain as a command.
Yes, be careful what you say to yourself. Our self-talk conditions us subconsciously just like water torture. (No, I don’t mean water-boarding!) Water torture is when you let a drop of cold water hit a person’s forehead. After a few of these you may be thinking this is ineffective torture – it’s just water drops. But after a hundred, a thousand or more, it is like a spike being hammered into your skull! So is the result of a negative or self-defeating comment said to you by someone else or by yourself (self-talk) on a regular basis. For example, if you say these things: “I’m getting fat. Do you think I’m getting fat? I’m too fat.” Or if you hear “you look fat” etc. then what do you think will be the result? Your conscious brain will program yourself to believe you are heavier than you actually are and that everyone must think the same. Can you see how dangerous this is? We all fluctuate in actual weight and appearance of weight daily, depending on meals, water, mirrors, scales and choice of wardrobe. You are no different!
Prevent this negative programming. Stop yourself when the negative self talk comes about. For help with this, check out other blog entries here (especially under the ‘confidence’ category) or take a look at my popular ebook (based on a popular coaching program!) called “Communicating Confidence Inside & Out – how to build confidence, be assertive and succeed!”
